I've been paying attention to the airbox and air filter as I try to track down the cause of the unstable idle.

I asked Lawrie at Williams how to remove the air box cover and he said there are either Hex or Torx bolts down under the rubber plugs, plus the 2 in Franks photo.

I've not yet had a look, that is a job for this weekend, along with cleaning the mass flow sensor.
